Title: Randon by face
Post by: Alexandre Besson on 2019-12-05, 13:00:21
Hi,

It would be nice to ad random by face to CoronaMultiTexMap and CoronaUvwRandomizer.

Regards

Makes sense! Will look into it.

Did not even thought this is technically possible. But it would be very very useful.


Good Luck

I guess the current workarounds would be:
- assigning random Material IDs to all faces and then using the randomization by Material ID
or
- exploding all faces into separate mesh elements

Anyway,

I know of no vanilla way to do this but manually <- And that's the evil word :] Or using a script. Additionally you would fail when having a multisub material applied to the object.

- exploding all faces into separate mesh elements

Not seriously. Usually you work with parameterized geometry and you would need to destroy the whole stack. Additionally, everything else like normals / smoothing / unwraps etc. may break when doing so. Imagine a box you create with segments set to something higher than 1 as an example. Try to randomize the polygons ("faces").

If it would be technically possible to treat polys ("faces") similar to "Mesh Element"s in Corona MultiMap - that would be absolutely amazing but I fear it is not as easy.


Good Luck

could be achieved using PTEX but is this even a thing anymore.
